Curved display panel manufacturing method

Abstract

A curved display panel manufacturing method for manufacturing a curved display panel having a curved shape using a flat display panel having a first substrate and a second substrate facing one another includes: paring partially outer portions of the first substrate and the second substrate so as to reduce thicknesses thereof to predetermined thicknesses; and forming fixing layers at edge areas which are not bent in a state of being bent to the desired curved shape among the edge areas of the first substrate and the second substrate.

Description

TECHNICAL FIELD [0001]The present invention relates to a curved display panel manufacturing method for manufacturing a display panel having a curved surface.BACKGROUND ART [0002]Various display devices have been developed and are being used. A liquid crystal display device which realizes images using liquid crystal is widely used.[0003]Generally, a liquid crystal display (LCD) includes two display panels and a liquid crystal layer disposed therebetween and having a dielectric anisotropy. An electric filed is formed in the liquid crystal layer, and a transmittance of light passing the liquid crystal layer is regulated by regulating amplitude of the electric field so as to obtain a desired image. Such a liquid crystal display is representative one of a flat panel display (FPD), and TFT-LCD which uses thin film transistor (TFT) as a switching element is widely used.[0004]A plurality of display signal lines i.e., gate lines and data lines, a plurality of thin film transistors and pixe...

AI Technical Summary

Benefits of technology

The present invention relates to a method of forming a curved display panel. The technical effect of this invention is that fixed layers are formed on edge areas near edges which are not bent in a state of being formed to the desired curved shape after paring the substrates. This prevents the collapse of cell gap which may be caused by the phenomenon that the two substrates are separated while the pared substrates are being bent so that the substrate which is disposed at a concave side of the curved display panel may be irregularly deformed.

Problems solved by technology

Such a liquid crystal display panel is generally manufactured in a flat shape, so the conventional liquid crystal display panel cannot be used as a curved display.

However, there is a problem that the manufacturing process of the conventional flexible liquid crystal display panel is difficult and the manufacturing cost thereof is high.

Such a separation of the two substrates may cause a phenomenon of collapse of a cell gap between the two substrates.
